Victor Stinner a6b9b071a3 Issue #19424: Fix a compiler warning 
memcmp() just takes raw pointers
 2013-10-30 18:27:13 +01:00
Victor Stinner 602f7cf0b9 Issue #19424: Optimize PyUnicode_CompareWithASCIIString() 
Use fast memcmp() instead of a loop using the slow PyUnicode_READ() macro.
strlen() is still necessary to check Unicode string containing null bytes.

Victor Stinner 68b674c9d4 Issue #19437: Fix _PyUnicode_New() (constructor of legacy string), set all 
attributes before checking for error. The destructor expects all attributes to
be set. It is now safe to call Py_DECREF(unicode) in the constructor.

Victor Stinner fa3ba4c3bc Issue #18609: Add a fast-path for "iso8859-1" encoding 
On AIX, the locale encoding may be "iso8859-1", which was not a known syntax of
the legacy ISO 8859-1 encoding.

Using a C codec instead of a Python codec is faster but also avoids tricky
issues during Python startup or complex code.

Victor Stinner e699e5a218 Issue #18408: Don't check unicode consistency in _PyUnicode_HAS_UTF8_MEMORY() 
and _PyUnicode_HAS_WSTR_MEMORY() macros

These macros are called in unicode_dealloc(), whereas the unicode object can be
"inconsistent" if the creation of the object failed.

For example, when unicode_subtype_new() fails on a memory allocation,
_PyUnicode_CheckConsistency() fails with an assertion error because data is
NULL.

cases, so _PyUnicodeWriter_Dealloc() can be called after finish.

so _PyUnicodeWriter_Dealloc() can be called on the writer after finish.

Victor Stinner 1a7425f67a Issue #18203: Replace malloc() with PyMem_RawMalloc() at Python initialization 
* Replace malloc() with PyMem_RawMalloc()
* Replace PyMem_Malloc() with PyMem_RawMalloc() where the GIL is not held.
* _Py_char2wchar() now returns a buffer allocated by PyMem_RawMalloc(), instead
  of PyMem_Malloc()

Victor Stinner bb4503f61e Partial revert of changeset 9744b2df134c 
PyUnicode_Append() cannot call directly resize_compact(): I forgot that a
string can be ready *and* not compact (a legacy string can also be ready).

Victor Stinner 8f674ccd64 Close #17694: Add minimum length to _PyUnicodeWriter 
* Add also min_char attribute to _PyUnicodeWriter structure (currently unused)
 * _PyUnicodeWriter_Init() has no more argument (except the writer itself):
   min_length and overallocate must be set explicitly
 * In error handlers, only enable overallocation if the replacement string
   is longer than 1 character
 * CJK decoders don't use overallocation anymore
 * Set min_length, instead of preallocating memory using
   _PyUnicodeWriter_Prepare(), in many decoders
 * _PyUnicode_DecodeUnicodeInternal() checks for integer overflow

Victor Stinner 77282cb4f8 Cleanup PyUnicode_Contains() 
* No need to double-check that strings are ready: test already done by
   PyUnicode_FromObject()
 * Remove useless kind variable (use kind1 instead)

Victor Stinner f033510fee Cleanup PyUnicode_Append() 
* Check also that right is a Unicode object
 * call directly resize_compact() instead of unicode_resize() for a more
   explicit error handling, and to avoid testing some properties twice
   (ex: unicode_modifiable())

Victor Stinner a0dd0213cc Close #17693: Rewrite CJK decoders to use the _PyUnicodeWriter API instead of 
the legacy Py_UNICODE API.

Add also a new _PyUnicodeWriter_WriteChar() function.

Victor Stinner 247109e74d Issue #17615: On Windows (VS2010), Performances of wmemcmp() to compare Unicode 
strings are not convincing. For UCS2 (16-bit wchar_t type), use a dummy loop
instead of wmemcmp(). The dummy loop is as fast, or a little bit faster.

wchar_t is only 16-bit long on Windows. wmemcmp() is still used for 32-bit
wchar_t.
